l Referring to the construction illustrated in Figs. 1, 2, 3 and 4, the numeral 9 indicate's a spindle sup Orting bracket 1 shown as 'PI'OVldGd with a pronged base'end that is rigidly clamped to a tiered "10 that is rigidly'se'cur'e fQand connectsthe rear wardly extendedportions ofthe 'side bars 11 of the automobile frame. To'the upper end ofth'e-bracket 9, a horizontally projectsame, as shown, havinga rounded head portion 13 intermediately adjacent to the upper end of said bracket. I i 1 A demountable -rim' 14 of the usual or any well known construction is provided YVlth the customary pneumatic tire 15 .hav-' mg the conventional charging nipple-16. To

support such a demountable rim from the spindle 12, said spindle is provided with one or more radial arms. As shown in' Figs. 1, '2 and 4, there are. but one of these arms indicated by the numeral 17,. and this arm has a split hub 18'that engages the spindle and is firmly, but preferably detachably connected thereto by'bolts or machine screws 19.- At-its free upper end, the rim supporting arm 17 has a laterally and outwardly extended bearing flange 20 that directly engages the inner surface of'the upper'portion of the rimlet and directly supports the same. Preferably, this flange 20 is slotted or bifurcated, so that. the nipple 16 of the tire 15 may be passed therethrough;

A pair offreversely bulged concavo-convex p I disk-like clamping plates are applied on I the spindle 12, the one inward and the other outward of the arm 17. The inner or socalled back plate is indicated by the numeral 21 and the outer or so-oalled front plate is indicated by the numeral 22. These plates are preferably formed with reinforcing central portions in the form of thin cast shells 21 and 22, respectively. Also, in this preferred arrangement, the central portion 21 of the back plate is formed with a concave socket 23 that fits the rounded head 13 of the spindle 12 and mounts the back plate for a slight universal wabbling movement on the spindle, so that it will readily adapt itself to engagement with the demountable rim or the tire thereof.

The spindle 12 has a threaded outer end that is passed through .the reinforcing cen tral portion 22 of the front plate, and working on this threaded end of the spindle is a nut-acting clamping head 24 shown as provided with an arm 25 by means of whlch it may be rotated. The inner end of this clamping head 24 is preferably rounded for engagement with a" concave socket 26 formed at the hub of the reinforcement 22 of the front plate. Thus the back and front clamping plates 21 and .22 are so mounted that they will adapt themselves to the form and position of the rim or tire and exert equal pressure thereon at all circumferential points.

When the demountable rim is without the I tire the clamping plates 21 and 22 are directly engaged therewith and hold the same in position, but they have such radial projection from the spindle that when the tire is applied to the demountable rim they will engage the sides of the tire. Thus, it will be seen that the so-called clamping plates serve to hold the demountable rim whether with or without a tire section in position and against wabbling or rattling, but with the weight thereof carried chiefly on the radial supporting arm 17. Also, the said plates afford an inclosing receptacle which closes the space within the rim and affords a space that is adapted to be.utilized for carrying parcels, or the like.

To properly utilize the space between the clamping plates, a suitable parcel carrier is applied thereon; and preferably this parcel carrler 13 in the form of a woven wire I basket 27 one side of which is omitted, and 55.

that side directly secured to the lower portion of the back plate 21. Thus the parcel carrier or basket is, in! the arrangement shown, directly supported from the back plate, but indirectly supported from the spindle. In fact, the front side' of the basket shown as provided with a hole afforded by the'attached reinforcing ring 28 that is slipped over the spindle. Obviously, in applying the basket and back plate to the spindle or for removing either from the spindle, the arm 17 must be loosened on the spindle so that it will slide off from or onto.

the spindle.

The carrierldescribed is adaptedto be readily converted into one that will carry an extra wheel, but to do this, the arm 17 must be removed. from the spindle and,,0f

course, the basket 27 must be omitted or re moved.

Of course, to adapt the spindle 12 to carry wheels having large hubs,'auxiliary spindle devices, such as disclosed in in said companion application may be emp oyed.

When it is desired to cover the outer or threaded portion of the tire, this may be done by employing a flexible cover 29- (see Fig. 2*) applied over the tire and-having ts flaps-interposed betweenthe sides of the tire and rims of the clamping plates 21 and located inward of the greatest transverse cross section of the fiIBK-SQ-that they will clamp the tire on: its inwardly converging surface. This is important, first, because it seats the rims of the clamping plates on the inwardly converging portionof thetire and thereby assists in, centering the tire in re? spect to theplates; and in the second place,

when the tire cover is employed this arrangement provides means whereby, when the plates are tightened againstthe' cover,

they will pull the covertaut by crowding the edges thereof inward on the tire. v r -Fig. 5 illustrates a modification in which the spindle 12 is made integral with areinforcing center 21 of the back plate 21. The

said center 21 is bolted, or otherwise, rig- .idly secured vto a supporting bracket 9 which is not only held on the cross rod 10,

' but is bolted to the transverse rear bar 11 of the automobile frame.

Figs. 6 and 7 illustrate amodification or I extension of the-construction illustratedin Figs 1, 2, 3 and 4, whereby two demountable I'lIIlS may be carried on the spindle but dis penses with the parcel carrying basket andemploysthree arm structures for supporting i the demountable rims from the spindle. In this-arrangement in Figs. 6. and 7, the elements 9, 12, 21, 22 and 24 are the same as in -Figs. 1, 2,3 and 4, but to the threaded end of the maln spindle 12 is attached a supplemental or extension spindle 30. This supplemental spindle 30 has a threaded socket that isv adapted to be screwed onto the threaded end of the main spindle 12 and, at its pro1ecting end it has threads that are asaaeve adapted to bescrewed onto the t readed end of the supplemental spindle .30, as well as onto the end of the said s indle 12, and moreover, the front plate 22 is adapted to he slipped onto the said supplemental spindle. Preferably, and as shown, the reinforcing center 23 of the back plate has a lug 31 that engages a notch 32 in the head of the sup.- porting bracket 9 to prevent rotation of the back plate 21.

The three-armed rim supporting brackets I 33 have hubs 34. thatadapt them to 'be slipped onto the main spindle 12, and preferably, said hubs are slit at 35 to make them slightly contractible so that they may be firmly clamped on the spindle by means of nut-equipped bolts 36 (see particularly Fig. (3). Here it may be also stated that the internally threaded end of the supplemental spindle is preferably, likewise, split and adapted to be contracted onto the threads of the spindle 12 by means of nut-equipped bolt or machine screw 37 (see Fig. 7 At their outer ends, the arms of the brackets 33 are provided with projecting flanges 38 onto which the rims are adapted to be telescopiduced by tightening the clamping ri resisted cally slipped. The rims-14 are provided with the customary inwardly pressed circumferentially extended rims 14 The rib 14 of the inner or right hand member 14.

engages the projecting ends of the flanges 38 and limits the movement of the inner demountable rim toward the right or toward the back plate 21. Hence, the inner bracket 33, may be so set that under pressure prob 14 against the outer plate, the inner tire will be pressed but lightly against the rim of the back plate 21 and further pressure will be the inner or back plate 21 tot-be made of a lighter and Weaker structure than the front or outer plate. This is important because .it is desirable to have the supporting s indle as short as possible and this result can e attained only by giving the back plate less concavity than the front plate.

Fig. 8 shows a slight modification in which the arms of the brackets 33, at the inner or rear extremities of their flanges 38, are provided with projecting stop lugs 33 that engage the inner edge of the inner demountable rim 14.

The carrier shown in Figs. 6 and 7 is adapted to be quite easily converted into one that is adapted to carry two extra wheels. It requires, of course, that the brackets 33 be removed and would require some such form of supplemental or extension spindle and auxiliary spindle devices that are illustrated in my companion application. However, this re-arrangement will be made by the purchasing of very "few parts, inasmuch by said bracket 33. This permits as the bracket 9, the main spindle 12, the

structures of the wheels. Of course, if the tire or tires either of rims or wheels are deflated, the clamping plates will 'be forced against the rims by tightening of the clampmg nut on the'spind e so that even in that event, the runs of the wheels will be firmly held by the clamping plates with the weight thereof carried chiefly on the spindle.

To provide for the above described Wabblmg or self-seating action ofthe clamping plates against the rim or tire, the hole passages thereof, through which the spindle is passed, should be made slightly larger than the spindle.

What I claim is:

l. A carrier for demountable rims comprising mner and outer clamping plates, means for supporting a tire-equipped rim betweensaid plates, means for supporting said clamping plates from a vehicle independently ofthe rim and for forcing said outer plate toward said back plate td clamp the same against the tire, the rims of said clamplng plates being extended radially outward beyond the wheel rim but terminating inward of the greatest transverse cross section of the tire so that the rims of said plates will engage the tire on its inwardly conver ing surfaces.

2. A carrier or demountable rims comprislng inner and outer clamping plates mounted for limited universal wabbling movements to seat themselves against an interposed rim or t1re thereof, a bracket interposed between said clamping plates for supporting a demountable rim and a bolt connecting the central portions of said plates and provided with means for clamping the same against a demountable rim or the tire thereof.

interposed between said plates, isclamped against said tire by the marginal portions of said clamping plates.

4. A carrier for demountable rims comprising inner and outer clamping-plates, a bracket 1nterposed between'said plates for supporting a demountable rim between said plates, the said clamping plates projecting beyond the rim so that they will engage the sides of a 't1re carried thereby, a flexible tire cover which, when applied around the tire is interposed between the sides of the tire and the margins of said clamping plates, and means for clamping the said plates against Y the 'tire.
